Rain Detector

The Rain Detector is based on the capacity principle. The capacity value of the sensitive element changes according to the surface dampened by raindrops. An integrated heater keeps it dry, evaporates water and prevents false signals caused by fog or dew.

The Rain Detector is equipped with three different outputs: a rain on/off output which detects whether it is raining/snowing (on) or not (off), also used to control a relay coil or similar devices; a 0...1V voltage analogue output (calibrated) and a 1,5...6KHz frequency output (not calibrated), which provide an accurate indication of current precipitation intensity. The on/off output comes with a delay circuit that indicates the â€œrain overâ€� condition with a 2 minute delay so that the â€œrain overâ€� condition is distinguished from the â€œlight rainâ€� one.

Optional BlinkerBeam® Wireless Communication

Systems can be activated and controlled with BlinkerBeam® self-powered wireless transmitters and receivers. These compact controllers activate systems wirelessly within a 1000 ft. range line of site (longer distances available with external antennas). BlinkerBeam® can be activated and controlled from a remote location, allowing for immediate implementation of warning, emergency and evacuation systems. Electric grid independence provides activation during power outages and remote locations.
